The size of the digester volume (usually the effective volume, ie the net volume of the main tank) should be determined according to the type, quantity, gas consumption and gas production rate of the raw material for daily fermentation, taking into account the amount and use of biogas fertilizer.
In this category, you will find Blood collection tubes and compatible accessories for drawing blood with aspiration systems.
Collecting the blood with Vacuumed blood tube is a significant improvement over the traditional blood collection method. Because it is a complete closed system to complete the Blood Collection procedures, thus fundamentally ruled out the possibility of blood contamination and cross-infection. As its simple structure is very easy to use, it is very popular now. Of course, considering the cost and need, we also supply Non-Vacuumed Blood Collection Tube. Micro Blood collection tube serves to the blood examination which just need a little blood.
Yingmed also supply Blood lancet for collect blood to test blood glucose.

In rural areas, the average daily gas consumption per person is 0.3 to 0.4 cubic meters. A family of four people cooks rice and lights for about 1.5 cubic meters per day. If you use good quality biogas lamps and biogas stoves, the consumption of gas can also be reduced.
According to scientific experiments and local practices, it is generally required that the average amount of feces (about 5 kg) of a pig enters the pond for fermentation, ie, an effective volume of 1 cubic meter is estimated to be built. The volume of the pool can be specifically planned based on the local temperature and the source of fermentation raw materials. In the cold winter in the north, the gas production is lower than that in the south. The average household pool is 8 cubic meters or 10 cubic meters; in the southern area, the household pool is about 6 cubic meters. Biogas digesters constructed in accordance with this standard are well managed and the biogas produced during the spring, summer and autumn months can be used in addition to cooking, boiling water, and lighting. Winter temperatures drop, and gas production decreases, but gold is used. Baby biogas fermentation aids can still maintain the fermentation effect.
Some people think that "the larger the methane pool is, the more gas is produced." This view is one-sided. Practice has proved that there is no gas is the "build" (build pool), more gas is less "pipe" (management). Although the capacity of biogas tanks is large, if the raw materials for fermentation are insufficient, scientific management measures cannot keep up, and gas production is not as good as that of small tanks. However, it is not only convenient to consider management, and the biogas pool is very small. Because the volume is too small, it affects the function of storing and fattening the biogas digester, which is also unreasonable. In addition, the rational use of biogas fermentation auxiliaries and biogas fermentation rotants in the management of biogas digesters can also greatly increase the biogas production rate and gas production rate.
